This was my son's first Halloween and it was a bit chilly out, so the costume worked great for putting clothes on underneath it as well. The mouth was a bit small for my son's face, but I wouldn't consider that a con. My only mistake was I purchased it on sale during the summer and my son grew so much that I wasn't able to fasten the bottom. Other than that, he was absolutely adorable in it and I'm very happy with my decision to get it for his first Halloween.
